摘要：This paper examines the relationship between separability of the direct production function in inputs and separability of the indirect production function in input prices. In particular, it shows that simultaneous direct and indirect weak separability implies homotheticity of the direct production function, and hence homotheticity of the indirect production function. Thus, inferences regarding direct separability based on empirical tests for indirect separability would be valid only if homothe...

摘要：I merge a model of monopolistic competition in the production of intermediate goods with the Shapiro-Stiglitz model of efficiency wages to show that the introduction of international trade leads to increased employment in both countries. The intuition is that trade results in a greater division of labor due to the increased variety of available intermediates. The resulting increase in productivity yields higher real wages, thus relaxing the efficiency-wage constraint and permitting an increase...
